Five people were arrested as fights broke out and at least one American flag was burned Saturday after a college Republican rally in Seattle drew counter-protesters.

College Republicans at the University of Washington had invited members of Patriot Prayer, a group in Vancouver, Wash., to speak in the university’s Red Square for a “freedom rally,” the Seattle Times reported.

The goals were to bring conservatives together and promote free-speech rights, College Republicans President Chevy Swanson told the Times. As the event got underway, supporters chanted “U-S-A!, U-S-A!,” and signs included one that read, “We died for liberty not socialism.”

But more than 1,000 counter-protesters showed up to oppose the event.

“I learned that they thought my vote was a hate crime,” Kathryn Townsend, who said she voted for Donald Trump in 2016, told Seattle’s Q13 Fox.
